AI video · How Founders Use AI

How are founders making product demos, ads, and social video with AI (Veo, Runway, Kling, HeyGen, ElevenLabs)?

The playbook now: write the script yourself, have Gemini or ChatGPT turn it into a shot-by-shot prompt list, generate clips with Veo 3.1 or Gemini Omni Flash inside Google Flow, Runway, or Kling 4.0, then cut it together in Premiere, Descript or DaVinci Resolve with an ElevenLabs voiceover. Omni lets you fix a clip by describing the change instead of generating it again. The reference case is Kalshi's NBA Finals ad, made by one AI filmmaker in three days for about $2,000. For SaaS product demos, founders skip generation and pair real screen captures with AI demo tools like Supademo, since showing the actual product beats synthesizing it.
